Abstract
The utility model discloses a kind of automatic rotation positioning fixture, base plate be provided with some groups of fixture modules, the work top often organizing fixture module by they sup-port on base plate; Cylinder is vertically fixed between work top and base plate, is positioned at the central authorities of work top, and pressing plate central authorities are fixed by joint pin and piston rod, and pressing plate is orthogonal with cylinder forms T font; The gear teeth are fixed on the central authorities of work top, are positioned at the circumferential position of joint pin, the gear teeth are processed with the tooth be meshed with the teeth groove of gear workpieces; Locating shaft is vertically fixed on the right position of work top, parallels with joint pin.The utility model is easy for installation, not only simplify workpiece and to feel relieved in clamping process the trouble complex process of contraposition, can also guarantee the crudy of workpiece, improve the qualification rate of product, save the clamping time, increase work efficiency, reduce labour intensity.
Description
Technical field
The utility model relates to field of machine tool fittings, especially a kind of automatic rotation positioning fixture for Gear Processing.
Background technology
Workpiece is subject to the effect such as cutting force, inertia force at mechanical processing process, easily vibrations and displacement occurs.In order to ensure that workpiece can keep the determined Working position of setting element, workpiece reliably clips by the general clamping device that adopts.In prior art, usually use common pressing plate workpiece pressing, but often dismounting pressing plate, with to locate the work clamped very long for non-cutting time, even far exceed the actual process time in workpiece, causes operating efficiency low.
Utility model content
The applicant is complicated for above-mentioned employing common pressing plate fixation workpiece clamping, and the shortcomings such as inefficiency, provide a kind of automatic rotation positioning fixture rational in infrastructure, thus simplifies clamping process, increases work efficiency.
The technical scheme that the utility model adopts is as follows:
A kind of automatic rotation positioning fixture, base plate is provided with some groups of fixture modules, the work top often organizing fixture module by they sup-port on base plate; Cylinder is vertically fixed between work top and base plate, is positioned at the central authorities of work top, and pressing plate central authorities are fixed by joint pin and piston rod, and pressing plate is orthogonal with cylinder forms T font; The gear teeth are fixed on the central authorities of work top, are positioned at the circumferential position of joint pin, the gear teeth are processed with the tooth be meshed with the teeth groove of gear workpieces; Locating shaft is vertically fixed on the right position of work top, parallels with joint pin.
Further improvement as technique scheme:
Described cylinder is rotary cylinder, the built-in 90 ° of helicla flutes of cylinder.
Described base plate is provided with some groups of fixture modules, use gas path plate to carry out gas circuit between any two and be communicated with and control, base plate both sides are provided with the U-type groove be fixed on the working face of lathe.
The beneficial effects of the utility model are as follows:
The utility model utilizes built-in 90 ° of spiral fluted rotary cylinders, the gear teeth are relied on to position machining gears, conveniently can realize the location of tooth to tooth, pressing plate is connected with screw by connecting rod with cylinder, can realize moving up and down and carry out 90 ° of rotations simultaneously, the installation carrying out processing work when not dismantling pressing plate can be realized, and realize automatic impaction in pressing plate moves downward.The utility model is easy for installation, not only simplify workpiece and to feel relieved in clamping process the trouble complex process of contraposition, can also guarantee the crudy of workpiece, improve the qualification rate of product, save the clamping time, increase work efficiency, reduce labour intensity.

Fig. 1 is stereogram of the present utility model.
Fig. 2 is the sectional view of Fig. 1.
In figure: 1, base plate; 2, gas path plate; 3, U-type groove; 4, support bar; 5, work top; 6, cylinder; 7, locating shaft; 8, the gear teeth; 9, gear workpieces; 10, pressing plate; 11, joint pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1 and Figure 2, the base plate 1 of automatic rotation positioning fixture described in the utility model is provided with some groups of fixture modules, use gas path plate 2 to carry out gas circuit be between any two communicated with and control, base plate 1 both sides are provided with U-type groove 3 for realizing fixing on the working face of lathe.The work top 5 often organizing fixture module is supported on base plate 1 by four support bars 4; Cylinder 6 is vertically fixed between work top 5 and base plate 1, is positioned at the central authorities of work top 5, and pressing plate 10 central authorities are fixed with piston rod top by screw, joint pin 11, and pressing plate 10 is orthogonal with cylinder 6 forms T font.The cylinder 6 that the utility model is selected is rotary cylinder, and the built-in 90 ° of helicla flutes of cylinder 6, piston rod band dynamic pressure plate 10 completes the motion of 90-degree rotation while oscilaltion.The gear teeth 8 are fixed on the central authorities of work top 5, are positioned at the circumferential position of joint pin 11, the gear teeth 8 are processed with the several teeth be meshed with the teeth groove of gear workpieces 9.Two locating shafts 7 are fixed on the right position of work top 5, parallel with joint pin 11.
During real work, connect source of the gas, piston rod rises, 90-degree rotation simultaneously, thus exposing two locating shafts 7 of both sides, the gear workpieces 9 of required processing is enclosed within locating shaft 7 periphery by operating personnel, and the teeth groove of gear workpieces 9 is meshed with tooth on the gear teeth 8 thus completes Workpiece fixing fast.Then piston rod declines, band dynamic pressure plate 10 spinning reduction, and last pressing plate 10 liang corrects the top side end face of Contact Tooth wheel workpiece 9 and compresses workpiece.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, when without prejudice to the utility model spirit, the utility model can do any type of amendment.
